[0022] The utility model, by setting an atomizer 6 arranged in the water tank 4, can make the nozzle 7 spray water mist through the atomizer 6, and diffuse it into the room of the workshop under the blowing of the wind in the exhaust duct 1, so that the air humidity in the room is neutralized, so that static electricity is not easy to be generated in the room, and dust explosion is avoided, so that the indoor humidity of the workshop is suitable, which is beneficial to people's health and comfort, and improves production efficiency and product qualification rate. By setting a liquid level sensor 10 and a solenoid valve 11, it is convenient to cooperate with the real-time water level information detected by the liquid level sensor 10 through the preset water level information, so as to intelligently switch the solenoid valve 11, so that the water level in the water tank 4 is always in a state that can support stable atomization, and can effectively reduce the daily maintenance cost of manual water addition.

[0023] Reference Figure 1 As shown, in this embodiment, a mounting frame 2 is sleeved on the exhaust duct 1, and the mounting frame 2 is fixedly connected to the external mounting surface through a fixing assembly 3. By setting the fixing assembly 3, the exhaust duct 1 can be effectively arranged in the air with the mounting frame 2. In the daily installation process, the fixing assembly 3 usually adopts a fixing bolt or an expansion bolt assembly.

[0024] Reference Figure 2As shown, in this embodiment, the middle of the exhaust channel 1 is connected to the sewage channel 9, and an inner recess 8 is provided on the inner cavity wall of the exhaust channel 1 between the two water tanks 4, and the inner recess 8 is connected to the sewage channel 9. When the water mist sprayed by the nozzle 7 contacts the dust in the exhaust channel 1, the water mist will adhere to the dust and settle on the lower cavity wall of the exhaust channel 1. At this time, due to the provision of the inner recess 8, the water droplets adhering to the dust can slide along the inclined cavity walls on both sides of the inner recess 8 into the sewage channel 9, and then the dust accumulates in the inner cavity of the exhaust channel 1, which affects the subsequent exhaust and dust removal and affects the dust content in the workshop.
